Windows Phone 7.8 demoed on the Nokia Lumia 510

The above video shows a brief demo of Windows Phone 7.8 on the Nokia Lumia 510, released in China recently.

The update of course brings the new start screen, but also new accent colours, Bing lock screen wallpaper, and on Nokia handsets SMS drafts and the ability to keep WIFI active when the device is suspended.

There are also rumours of the ability to send files via Bluetooth File Transfer, unfortunately not demonstrated.
